Gearbox released a free DLC for Borderlands 4 titled 'How Rush Saved Mercenary Day,' which includes a new boss fight, legendary loot, cosmetics, and story missions. The game's peak concurrent users on Steam this week was 15,887, unchanged from the previous week and down from earlier this month. Despite improvements over its predecessor, player engagement has declined, with many players feeling a lack of motivation to return. The DLC is perceived as a lighter addition, and Gearbox's promotion of it has been insufficient. Players who purchased the deluxe edition will receive an additional bounty pack. Performance issues on lower-end PCs further deter players. Upcoming content, including a full Story Pack DLC featuring Mad Ellie and a new Vault Hunter, C4SH, is anticipated to boost interest.
